Yes the stock lights are bad especially after they haze over. Before I switched mine out I was using my spot lights to try and see where I was going.
I couldn't find an LED replacement light for my F250 that were made by a company I had heard of so I replaced mine with some less expensive units.
This is what I ended up with, and I'm very happy with them.
Regarding LED lights in general. The quality of LED lights varies from excellent to poor even though a high quality brand like BajaDesigns look the same as the no name brand. We were at a show in Phoenix recently and the booth across from us sold LED lights, when I went over to look at them the sales pitch to me was the low price, the dealer margins, and the fact that if and when they stopped working the unit would be replaced no questions asked. When I asked them which LED they used, what the light pattern, penetration, and color was they couldn't answer my question.
Later I strolled over to the Rigid Industries booth asked them the same questions and had them all answered in depth.
It's extremely difficult to judge LED lights on looks alone.
